Carboxylic Acids

Question 1

what functional group do carboxylic acids contain

Answer 1

COOH

Question 2

What carbon is the functional group and why

Answer 2

Carbon 1 as is the highest priority functional group

Question 3

What sort of acid is a carboxylic acid and why

Answer 3

Weak acid as it only partially dissociates in water

Question 4

Where does equilibrium lie in carboxylic acid dissociation and why

Answer 4

Lies to the left as most molecules don’t dissociate

Question 5

What forms when carboxylic acids react with carbonates

Answer 5

Salt, water, carbon dioxide

Question 6

Why can carboxylic acids dissolve in water

Answer 6

They can form hydrogen bonds to water molecules

Question 7

What makes a carboxylic acid a weaker acid and why

Answer 7

Increasing chain length as alkyl groups push electron density onto COO- ions, making it more negative energy and less stable

Question 8

What makes a carboxylic acid stronger

Answer 8

Electronegative atom on chain draws electron density away from COO- ion, making it less negative and more stable
